  • Patent number: 11146838
    Abstract: A system and method for operating a communication network having one or more cable modems. Operating the communication network may include displaying one or more messages to a subscriber and making temporary changes to Cable Modem Termination Systems in order to modify the availability of network resources for one or more cable modems assigned to a subscriber without requiring a rebooting of the one or more cable modems.
    Type: Grant

  • Patent number: 10868724
    Abstract: An unregistered cable modem is in a cable operator network having a computer, a dynamic host configuration protocol (DHCP) server, a spoofing domain name system (DNS) server and a good DNS server, a captive portal application, and a trivial file transfer protocol (TFTP) server. The cable modem is provisioned by the cable modem obtaining a configuration, rebooting, and activating the configuration. The computer obtains a plurality of computer configuration parameters including an IP address of the spoofing DNS. The spoofing DNS server answers an HTTP request from the computer with an IP address associated with the captive portal application. The captive portal obtains an activation code from the computer, verifies the activation code is correct, and forces the cable modem to reboot.

  • Patent number: 10757099
    Abstract: A system and method for detecting fraud in a network is disclosed. The network includes cable modems, a network collector, cable modem termination systems (CMTS), and a network data converger. The network collector scans a first cable modem and receives and sends to the network data converger device identification for the first modem and an address of a first CMTS connected to the first cable modem. The network collector adds this information to a devices inventory. The network collector scans a second cable modem and receives and sends to the network data converger device identification and an address of a second CMTS connected to the second cable modem. The network data converger compares this information to the information in the devices inventory and may determine fraud based on the comparison.

  • Patent number: 10496397
    Abstract: A method for updating firmware of cable modems optimizing management resources in a network comprising a web application, network collector, more than one cable modem, one or more servers. The method includes the web application receiving an update firmware policy, the policy defined by a list of cable modems to have their firmware updated, a Uniform Resource Identifier (URI) pointing to a file within a server in the network, and the web application adding a policy with this information to a policies table. The network collector polls a database engine for a new policy and computing a list of cable modems to have their firmware updated, and the network collector sends a command to a cable modem to update to a new firmware, wherein the new firmware is specified by the URI.
